Unit 7 The Sea你知道海水为什么是咸的吗？它会不会变淡或者变得更咸呢？Have you ever noticed that，in the summer，when your sweat dries it will leave marks on your T­shirt？ 1If you go to the seaside，you will know that seawater does the same to your clothes，because it also has a lot of salt in it.Water evaporates (蒸发) from the surface of the sea but the salt remains. Have you ever thought about whether the seas will keep getting saltier? The answer is no. The oceans have stayed at about 3.5 percent salt content for hundreds of millions of years. 2The outer hard crust of Earth is made up of a dozen or so hard plates that drift (漂流) on extremely hot，soft rock like floating islands on asea. The heat within Earth is not the same everywhere and the plates move due to the heat.When an ocean plate bumps into a land plate，the less dense land plate floats over the ocean one. The ocean floor gets pushed under，and its salty rocks，along with shells and bones，are lost deep within Earth.So， 3根据短文内容，从下面所给选项中选出能够填入空白处的最佳选项。

Unit 7 The SeaKiller whales have the second­heaviest brains among marine mammals (after Sperm whales, which have the largest brain of any animal). They can be trained in captivity (囚禁；关押) and are often described as intelligent, although defining and measuring “intelligence” is difficult in a species whose environment and behavioral strategies are very different from those of humans.Killer whales imitate others, and seem to deliberately teach skills to their kin. Off the Crozet Islands, mothers push their calves onto the beach, waiting to pull the youngster back if needed.People who have interacted closely with killer whales offer numerous anecdotes demonstrating (证明) the whales' curiosity, playfulness, and ability to solve problems. Alaskan killer whales have not only learned how to steal fish from Iong lines, but also have overcome a variety of techniques designed to stop them, such as the use of unrated (未分级的；未征税的) lines as decoys. Once, fishermen placed their boats several miles apart, taking turns retrieving (恢复；取回) small amounts of their catch, in the hope that the whales would not have enough time to move between boats to steal the catch as it was being retrieved. A researcher described what happened next: The killer whale's use of dialects and the passing of other learned behaviours from generation to generation have been described as a form of animal culture.Section_ⅠWarm­up__&_Lesson_1_—_Pre­reading[原文呈现]VIKING VOYAGES①TO AMERICAThe Vikings② were the first Europeans to reach America③.
